Beschreibung
Zusammenfassung:	A tri-leaflet valve 100 for a prosthetic heart valve is provided. The tri-leaflet valve 100 has three leaflets 102 and is made from polymeric material. Each valve leaflet 102 has an attachment edge 104 along which it is attached to a surface of a support stent, a free edge 106 and a belly 108 extending between each free edge 106 and attachment edge 104. The attachment edge 104 of each leaflet 102 is generally arc-shaped wherein the arc-shape is defined by a plane, a cylinder or a cone intersecting a cylinder or a cone, and the length of the free edge 106 of each leaflet 102 is equal to or greater than an arc of radius R between the two points on the attachment edge 104 where the free edge 106 intersects the attachment edge 104, where R is the radius of the tri-leaflet valve 100. The invention extends to a mould and a method for manufacturing a polymeric tri-leaflet valve involving spraying the polymer onto the mould.
